. struction and which possesses a high degree g comfort when used eitheras a sofa or a A further object of the invention is to provide a`folding bed. in 'which the mattress framesor supports are independentlymovable in ne position and comointly movable in anothenposition.

. The invention possesses other advantageous features, some of which,with the fore y going, will be set forth at length in the followingdescription where I shall outline in full that form of the inventionwhich I have Selected for illustration inthe drawings accompanying andforming (part of the present specification'. In said ravvings, I haveshown one specific form of. my generic in "ventiombut it is to beunderstood that I do not limit myself to such form because my inventionmov be embodied in a multiplicity of forms, een; being a species of mysaid invention.' It is also to be'nnderstood that by the claimssucceeding the description of my invention, I desire to cover theinvention in whatever form it may beembodied. f Referring to saiddrawings, `Figure l 'is a i vertical section of the `bed in the foldedposition, the bed springs being removed to bet* ter disclose Atheconstruction.

In the drawings I have shown a one-fold bed and a twofold bed, theconstruction of the two-fold bed being similar tothat of the one-foldbe'd with the exceptonof the additions necessary to effect the operationof the two-fold bed. I shall first describe the onefold bed and then theadditional features of the two-fold bed.

'When the invention is embodied in a davenport, the device consists of asuitable stationary body comprising a base-2, the sides 3 and the backf1 which may or may not be upholstered desired. The back is stationaryand is arranged at the upper por-l tion of the body only, allowing-thespace Within the hodv and below the back to-bo used for receiving thefolded bed. One of' the objects of this invention is to so arrange thebed frames, that when they are folded within the body, sulticicnt space'is provided for an upholstered mattress, and so that the seat is not toohigh to` be comfortable. Ar`- ranged in the body are two Amattressframes 5 and G, the, upper fra-me 6 being provided' on its upper sidewhen folded with a seat 7, preferablv upholstered. Secured to the underside of frame 6 are a plurality of coil springs 8 which are connectedtogether at their free ends by a fiexible 'metallic structure 9,producing a springjmattress Secured to the upper side of frame 5 are aFig. l1 is a vertical i so other, the frame is turned over, so that whenunfolded, the mattress formed 'by the springs 8 lies on the upper A'sideof the frame and the seat 7 lies below the frame. thel frames iand (3are' in the folded or superposed position, sufficient space is leftbetween the structures 9 and 13 to accommodate a folded upholsteredmattress 11, and the upper frame is vsupported at its inner end by stops15 secured to the sides 3.

Means arey provided whereby the bed may be easily unfolded, the weightot' the upper frame serving during part of its movement to raise orassist-'in raising the lower frame to its operative level. 1n order thatthe fdlded bed may li'e as-closc to the Iloor as is possible, the lowerframe is movable from an elevated position when in use as a bed, to adepressed position when folded. In the opening or unfolding movement ofthe bed,

the upper frame is movable independently ,edge of the frame. The plate16 is provided with a slot 19 concentric with the pivot 1'8 and disposedin this slot isa pin 21 which is secured to .the upper frame. The slot,in the present construction, lsubtends a'n angle of 90 degrees,permitting the upper frame to be moved 4trom-the position shown in Fig-1to the position shown in Fig. 3, without producing any movement of thelower frame 5.

Fixed tothe pivot 18 (Fig. 13) which is fixed to the-'plate 16 is astrong coiled leaf spring 22, the free end otwhich presses against thepin 21 and assists in raising the upper frame 6 from its horizontal.folded position. A' disk 221 secured to the end of the pin insuresengagement between the pin and the spring. v

The lower frame 5 is supported at the opposite ends on links v24-g2fi,which are pivoted to the side' or other stationar)vv part ot thestructure, the links heingsimilarl;7 disposed so that the frame remainshorizontal as it is moved. Connected to the pivot between the link 25andthe frame is a link 26 which ispivoted-at its other end to the plate16. in such position that as the plate is luovcd about its pivot 17. thelink fis mo` ed to a. substantially vertical position. T n order toaccomplish this movement and 'to prevent the links and parts frombinding, the rear end of the frame 5 is-lifted by the link 27, which vispivote'd at.

lV hen one end' to the link pin at the rear end of the frame and at theothervend to the plate 16.

The link 27 is provided) with a slot 28 in which the link pin on theframe engages, so that as the platelt is moved, the llnk 27 is raisedabove the fixed pivot of the link 24 before it exerts its raising efforton the frame.

The lower frame in raising swings about the fixed link pivots and sweepsforward and upward in van are, so that in its raised position it extendsout over the base board 29, and the inner edge of thc frame swingsforward and clears the back 4. lVhen in the l unfolded position theframes 5 and 6 abut against each, other and are alined, and the mattresssurfaces 9 and 134 are alined.

The upper or folding frame, is supported at its outer end, whenunfolded, by legs .31 which are pivoted to the frame in such manner thatthey are substantially rigid when in contact with the floor. The legsare slotted at their upper ends and engage pins 32 on the frame. Securedto the frame above the pin 32 Aarc two stops A33 between which theupperend of' the leg slides-and the stops prevent the leg from`.mo'vingabout the pin when the leg is in contact with the floor, and'one of the.stopshol-ds the leg parbackward and assists in raising the upper framelfrom' its unfolded horizontal' position. In order to'prcvent theupholstery 36 from folding up -and getting caught hetwecn the two frameswhen they are unfold- Aed, I provide means for pushing the upholsteryoutward and away from the frames. This means consists of a projection 3Ton lcae-h plate 16 and a w'ire or rod 3S connecting the projections.

In Figs. 8 to'12 inclusive I have shown the invention as'applicd to a.two-fold bed. In this construction. instead of employing the coilspringr mattress. as inthe prior construction. l employ a linkedmetallic structure 40.which is supported h v coiled springs 41 .attachedtothe. frames. The construetion of the lower frame 5 remainssubstantially as before, with ,the exception that the `links` 2l and 25vare made'longer, whereby the frame 5' is raised to a greater height. Secured to cach ,side rail of the frame (i, by suitablev supports 42, archars 43 which, when the bed is unfolded,` arealincd with ment.l

the side rail 'Lof the frame 5, forminga continuation tti reofand towhich the metallicl fabric 40 is attached. Secured to the ends of theside rails ofthe frame 5 are blocks 44 which project from the siderailson the under side and form seats and supports for the rails 43,insuring their alinement with the side rails of frame 5. I"

Attached to the rails 43 at their outer ends is the folding frame 45 whilh is foldable from `a positlon ofsuperpos tion with relation totherails 43 to a )osltion of alineends is a segmental gear 46, which isengaged by `a similar segmental gear 47 secured to the end of the sideyrail or frame 45. Passing through tle center of each segmental gear isa pin and the pins are connected,

by the links 4E1 whereby the gears are held in mesh. Bv employing thisform of connection, the fabric 40 is pulled taut as the frame' 45 isunfolded. When the frames 43 and 45 are alined, the link 48 lies abovethe level of the fabric 40, so that the tension of the fabric supportingsprings holds the l frame 45 from folding backward.

Pivoted to the frame 45 at-f its outer end are the legs 5l upon whichthe outer end of the frame is supported.` Attachedto each leg 51 and tothe frame 45 at a point adjacent the leg pivot 52 is a coiled spring 53.The points of attachment of the spring to the leg and to the frame aresuch, that as the legismoved from one positionto the'other, the springmoves past the pivot 52, thereby serving tc hold the leg either in itsfolded or operative position.` The spring 54, secured to the piyotfedfoot frame 55 is similarly arranged, so 'that it operates .to hold'thefoot board vertically, as shown in Fig. 14,

Y or operates topress it against the mattress,

in which position it operates as a clamp, as shown in Fig. 15. VA stop56 secured to the frame 45 rests against the frame 5, when the bed isfolded and supports the inner ends of frames 45 and 6.

Means cre provided for securing the frame 45 and the frame 43 together,so that they may be readily folded as one piece. Secured to each leg 51is an extension 57, which when lthe frame 45`is superposed on frame 43engages under a pin 58 on rail 43 when the leg is moved into parallelismwith the frame 45. This locks the frame 45 to the rails 43,-so that theframe may not move relatively to the rails. The legs 51 on oppositesides of the bed are preferabl Iconnected together by a rod 59, and when1t is desired to unfold the frame 45, the rod 59 is pulled, causing thelegs to swing about their pivots and thereby ul'llatching the lockingmeans, so that the frame 45 may be li ted over. i
